Application lerl July 3, 1512. Serial No. 707,594.

To all @fiom 'it may concern Be it known that We, JAMES VHITHNG- HILL and ELIJAH `W. RICHMOND, citizens of the United States, residing at Advance, in' the countyof Stoddard, State of Missouri, have invented a ne.r and useful Rotary En plosive-Engine, of which the following is a specification.

The present invention relates to i1nprovements' in rotary explosive engines, the primary object of the invention being the pro, vision of a novel form of stator and rotor, in whichA the cam periphery of therotor actuates the explosive Ycharge admitting piston and also the explosive chamber forming y blades or partitions, to at the propertime deliver the explosive charge into the rotor chamber, and compress the same, the explosion occurring at the desired point of compression and through any form of ignition system, which in thf present'instance is a jump spark system.

' .A further object'of the present invention is the provision of a novel form otrotary engine in which there occur three explosions and exhausts during ,each revolution of the rotor, the admitting ports being disj posed at diametrically opposite points, while the exhaust ports are also disposed at diametrically opposite points of the rotor chamber.

With the foregoing and other objects in view which will appear as the descriptionv proceeds, the invention resides in the combination and arrangement of parts andy in.AV

the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from thel spirit ofthe invention.

In the drawings Figure l is a central I transverse sectional view through the stator,

the rotor being shown in elevation and the parts in the position they assume when the compressed gas at one side of the rotor is about to be ignited. Fig. 2 is a section taken on line 2-2 ot Fig. 1 through the complete engine. Fig. 3 is a perspective view of the frame and the piston and blades operated thereby. jj

Referring to-the drawings, the numeral 1 designates the base of the engine which car ries the annular ring or band 2, which has .connected thereto by means ofbolts 3,'the

respective heads 4 and 5 of the engine,.said band 2 and the heads L1 and 5 constituting.

the stator ot the engine and providinga nar larged ends 9, each one of which is provided with the transverse groove or pocket 10 for thel reception of the packing strip 11, the spring 12 being provided to-norm'alrly hold the packing strip 11 outward and into contact with the inner rotor chamber.

In order to pack the outer faces lo`t`tlie peripheral wall oi. the l rotor 8, so as to produce a gas tight joint v between the res ective faces vand the inner walls ofthe heads 4 and 5, are the strips 13 which are disposed as shown in Fig. 1, and form a triangle. Each peripheral portion of the rotor 8 between the respective strips l9 are provided with the compound curved portions l5, 16 and 17, the same providing a plurality of cam surfaces upon the periphery of the rotor for the proper actuation of the various means for forming compression chambers within therotor and for permitting of the proper intake and exhaust of the explosive charges as will presently appear. Disposed to conduct the explosive charge to the respective cylinders 6 and 6 are the conduits 18 and 18 respectively, the same being disposed adjacent the. inner ends of 4the respective cylinders, While formed in the ring@ are the valve controlled intake ports 19 and 19 respectively, to permit of the in` traduction of the explosive charge into the chamber C, and to prevent any back pres` sure of such charge or the burnt gases.

In order that the compressed explosive charge may be ignited at the proper time, the `spark plugsQO and 20 are connected in the ring 2, as clearly shown in Fig. 1, While disposed for sliding movement within the outer end and concentrically of the chamber of the respective casings 6 and 6', are the piston rods 21, each one of which has disposed upon its inner end the piston 22, which acts as a. cut-ott for the respective conduits 18 and 18 and also as a means for torcmgl as s . explosive charge through the valve ports it? and i9 into the chamber C. A spring 23 is inounted upon the piston rod 2l between the head W and the outer end of the respective casi C or o, and normally exerts a tension to nwve the piston inwardly. )t hlade 2% connected to the inner end of the rod t and projects through the transverse slot- TZG toi-ined in the ring 2?., one to each 'ing 6 or o" and disposed upon the inner end of the partition or blade 2st-is a packstrip which is disposed to engage at all tiincs the peripheral sui-tace ot the rotor The explosive charge has been forced -by the piston 22 through the valve port 1S) and into the compression and explosive chamber il? formed by the inner pt ripheral rali of the ring 2, the partition and thc adjacent surface oi the periphery ol the rotor 8, the spart: plug E2() at this time being energized to ignite such. charge and thus propel the rotor in the direction oi the arrow lig. l.

ln order to iinpart posit-ive iiiovcznent to the respective blades or partitions and also theezipiosive charge supplying;` pistons 22, the guiding spider or iranie QS is inounb ed e-,zlerifn'ly o t' the stator and about the Y 7,'the 'said traine being provided with the oppiiisitely disposed links or rods 'Z9-95V, whose outer hooked ends 3() and 30 respectively, are connected to the extreme ends ot the piston rods 2l and exteriorly of the respeciive'casings ti and 6.

lt will thus be seen that as the. rotor o rotated.y and duc to the contacty ot' the inner end 2:3' of the blades or partitions 2l, that the cani surfaces oi the rotor 8 will iinpart the desired inward and outward morenients to the respective blades Bil and conso' quent ly the pistons 22, and as said pistons are coniufcted together for movement in unison.. simultaneous inoreu'icnt will be iin- ;farled thereto to cause the explosive charge in he admitted to the chamber C at the de edtirne and in such a manner, that three ssive explosions will occur each rot-n lion of the rotor 8. A

In order to properly exhaust the burnt gases from the chamber C, the two diametrically disposed exhaust ports 31 and 31 are provided in either head 4c or 5.

lt is evident that by cutting out the supnly ot carbureted air to one supply casing, that three instead of six explosions every ansioso revolution of therotor will result, this being entirely at the will of the operator.

Frein the foreooinf descri .Jtion taken ina hydro farben gas, and that with the present arrangement, three successive explosions and exhausts at each revolution of the rotor is produced. It is also evident that by reason of the cani surfaces of the rotor, that positive actions are imparted to the piston 29. and blades 2l, the inner ends 25 of the blades 9A being,r at all times eushionedly held due to the springs E23 in proper con tact with the periphery o the rotor, thus providing the desired. pressure duid tight joint therebetween, and that by the disposition of the casings (l and G, the movable elements of the engine are readily accessible.

What claimed is: A I

A rotary explosive envine, including a stator having a rotor cham er provided with two dian'ietrieally disposed 'intake v orts and two exhausty ports, a valve control ing each intake port, two abutments mounted Slidably at dianietrically opposite points in the walls ol the stator, an explosive charge supplying piston niounted in each casing and operably connected toits respective abut- .n1ent, a piston rod connected to each piston and projected exteriorly of its respective casing, a rod connecting the two piston rods for movement in unison, a rotor mounted in the casing,` and provided with a plurality ol cani surfaces upon its periphery, the inner ends ot' the two abutnients being in engagement with said surfaces, whereby the rotation of the rotor will simultaneously ac- 'tnate both sets of abutments and pistons, and a spring mounted in each casing upon its respective piston rod for 'normally moving its respective piston inwardly.

ilu testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
